Goals:
Find SOA yield for dodecane + Cl under high NOx condition (NO and NO2 injected) at RH=67%. Investigate volatility behavior based on 2D thermograms.

Summary:
Ammonium sulfate seed (0.01M, 150 mL) was injected using an aerosol generation system. Cl2 gas, NO and NO2 gas were injected from their cylinders. 90 ug/m3 of dodecane was injected into a glass bulb and heated clean air was made to flow over it, carrying the volatilized dodecane into the chamber. After ~30 mins (sufficient mixing time), lights were turned on for 1 hour. 98.9 ug/m3 of SOA was formed, giving a mass yield of 1.10. This is Exp#12 in associated publication.
